Answer:
x = 3
Step-by-step explanation:
To solve this equation, we can use basic algebraic techniques as illustrated.
3(x + 4) = 7x Distribute the 3.
3x + 12 = 7x Subtract 3x from both sides of the equation.
12 = 4x Rearrange the equation so the variables are on the left.
4x = 12 Divide by 4 on both sides of the equation.
x = 3
Answer:
3(x+4)=7x3x+12=7x7x=3x+127x-3x=124x=12x=12/4x=3Which two of the following are not characteristics of surveys?
4. Two or more treatments are compared in the study.
B. Data are gathered during the course of the study.
C. One or more treatment groups and a control group are included in
the study.
D. The results of the study are analyzed statistically.
Answer:
The following characteristics of experiments are not also characteristics of surveys:
- The first one is B. The study compares two or more treatments (possibly including "no treatment").
- The other one is D. The study involves one or more treatment groups and a control group.
Step-by-step explanation:
surveys are tested with one group
The two options are B) and C) because they are characteristics of science.
What are the characteristics of surveys?The main characteristics of surveys are as follows:

Answer:
[tex]x\approx12.1940[/tex]
Step-by-step explanation:
So we want to find the value of x.
To do so, we can use the standard trigonometric ratios.
Focus on Angle B. The opposite side is 8, and the hypotenuse is x. Therefore, we can use the sine function.
Recall that sine is:
[tex]\sin(x)=opp/hyp[/tex]
Substitute 41 for x, 8 for the opposite, and x for the hypotenuse:
[tex]\frac{\sin(41)}{1}=\frac{8}{x}[/tex]
Cross multiply:
[tex]8=x\sin(41)[/tex]
Divide both sides by sin(41):
[tex]x=8/\sin(41)[/tex]
Use a calculator:
[tex]x\approx12.1940[/tex]

Answer:
2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > [tex]\sqrt{300}[/tex], 300%
Step-by-step explanation:
Given numbers are,
2.38 × 10², √300, 2⁸, 300%, 6³, 2.16 × 10¹
We have to arrange these numbers in the decreasing order(from greatest to least)
2.38 × 10² = 2.38 × 100 = 238
√300 = 10√3 ≈ 17.32
2⁸ = 256
300% = [tex]\frac{300}{100}[/tex] = 3
6³ = 216
2.16 × 10¹ = 21.6
Therefore, decreasing order (from the greatest to least) will be,
256 > 238 > 216 > 21.6 > 17.32 > 3
2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > [tex]\sqrt{300}[/tex], 300%

Evaluate j/4 when j=12
Answer:
3
Step-by-step explanation:
[tex] \frac{j}{4} = \frac{12}{4} = 3[/tex]
4*3=12
3*4=12
12/4=3
12/3=4
Hope this helps ;) ❤❤❤
Answer:
We need to evaluate [tex]\frac{j}{4}[/tex] for j = 12.
First, we need to replace j by 12 on [tex]\frac{j}{4}[/tex], so we get [tex]\frac{12}{4}[/tex] and now, we only need to divide:
[tex]\frac{12}{4}=3[/tex]

f(x)= -X+6 g(x)=4x-6
g(f(x))
Answer:
[tex]g(f(x)) = - 4x + 18[/tex]Step-by-step explanation:
f(x) = - x + 6
g(x) = 4x - 6
In order to find g(f(x)) substitute f(x) into g(x) that's for every x in g(x) replace it with f(x)
That's
[tex]g(f(x)) = 4( - x + 6) - 6 \\ = - 4x + 24 - 6[/tex]We have the final answer as
[tex]g(f(x)) = - 4x + 18[/tex]Hope this helps you

The graph of a linear function is shown.
A coordinate plane with a straight line drawn passing through (negative 5, negative 3) and (5, negative 3).
Which word describes the slope of the line?
positive
negative
zero
undefined
Answer:
zero
Step-by-step explanation:
the slope of a function m: y2-y1/x2-x1
m=-3-(-3)/5-(-5)
m=0/10=0
The slope of the line drawn passing through (- 5, - 3) and (5, - 3) is zero, so option C is correct.
What is line?An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.
Given:
straight line drawn passing through (- 5, - 3) and (5, - 3)
Calculate the slope of the line as shown below,
[tex]m = y_2 - y_1 / x_2 - x_1[/tex]
m = slope
m = -3 - (-3) / 5 - (-5)
m = 0 / 10
m = 0
Therefore, the slope of the line drawn passing through (- 5, - 3) and (5, - 3) is zero.

where x is nonzero
=======================================================
Explanation:
We'll use two rules here
(a^b)^c = a^(b*c) ... multiply exponentsa^b*a^c = a^(b+c) ... add exponents------------------------------
The portion [ x^(a-b) ]^(a+b) would turn into x^[ (a-b)(a+b) ] after using the first rule shown above. That turns into x^(a^2 - b^2) after using the difference of squares rule.
Similarly, the second portion turns into x^(b^2-c^2) and the third part becomes x^(c^2-a^2)
-------------------------------
After applying rule 1 to each of the three pieces, we will have 3 bases of x with the exponents of (a^2-b^2), (b^2-c^2) and (c^2-a^2)
Add up those exponents (using rule 2 above) and we get
(a^2-b^2)+(b^2-c^2)+(c^2-a^2)
a^2-b^2+b^2-c^2+c^2-a^2
(a^2-a^2) + (-b^2+b^2) + (-c^2+c^2)
0a^2 + 0b^2 + 0c^2
0+0+0
0
All three exponents add to 0. As long as x is nonzero, then x^0 = 1
